The municipal coat of arms depicts a capercaillie from which the name Haninge is believed to have been derived (the German word hahn means capercaillie), while the anchor symbolizes the naval base in the municipality.

Haninge cherishes its nature, housing the southern parts of the scenic Stockholm archipelago.

Haninge is also an area with access to Tyresta National Park with a surrounding nature reserve.

It has been protected to preserve its noted natural values, e.g. one of the largest sections of untouched forest in southern Sweden.

This is a demographic table based on Haninge Municipality's electoral districts in the 2022 Swedish general election sourced from SVT's election platform, in turn taken from SCB official statistics.
